SPECIFICATION forming part of Letters Patent No. 5Q8,481, dated November14, 1893.

Application filed'J'anuary 9, 1893. Serial No. 457,843- .(No model.)

To all whom it may concern:

. Be it known that I, LUBPE LUPPEN, a citizen of the United States,residing atPekin, in the county of Tazewell and State of Illinois,

have invented certain new and useful Improvements in Cultivators, ofwhich-the foldetail, bein a section on line 77 of Fig.4..

Fig. 8 is a plan view of the disk gangs showing them arranged forthrowingthe dirt outward; and Fig. 9 is a rear view of the parts shownin Fig. 8.

My invention relates to cultivators, and particularly to diskcultivators.

' The objects of my invention-are to provide improved devices formounting the disks,

. ends of the spindles 23 and 24 with the ends whereby they may beeasily adjusted to the lineof motion of the cultivatorfor the purpose ofregulatingthe furrows; to provide means whereby the disks may bearranged for'throwing the dirt either in or out; to provide meanswhereby the depth of the fur-' rows may be regulated at pleasure, and toimprove the construction of cultivators of this class in general. Iaccomplish these objects as hereinafter specified and as illustrated inthe drawings.

That which I regard as new 'will be pointed out in the claims. I

1 wheel axle 12, wheels 13 and 14, seat bars 15 and16, draft bar 17, andbraces'18 and 19.

= The'draft bar 17'is mounted-upon the tongue 12 near its rear end inthe usual manner, and I is provided with depending hangers 20 near itsends, as shown in Fig. 1. The braces 18 and 19 extend from oppositesides of the tongue 11 to the wheel axle 12, to whichthey are connected,as best shown inFig. 2, and

serve to brace the tongue. The seat bars 15 and 16 are connected attheir forward ends to the braces 18 and 19, and carry a seat'21 at theirrear ends, as shownin Figs. 1 and 2.

22 indicates an arched axle which constitutes a front support for theframes of the disk gangs and is mounted upon the rear end of the tongue11. and providedwith spindles 23 and24 located in front of andslightly'below the spindles of the wheels 13 and 14, as

best shown in-Fig. l .25 and 26 indicate sleeves or pipe-boxes, mountedrespectively upon the-spindles 23 and 24, as shown in Fig. 2. Eachpipe-boxis I provided with one or more bolt-holes 27, by means of whichthe cultivator couplings may be coupled to the pipe-boxes, as will behereinafter described.

28'and' 29 indicate brace rods connected at their rear ends to the endsof the axle 22, and at their forward ends to the tongue 11, as shown inFig. 2.

30 and 31 indicate draft rods, connected at their rear ends to thespindles 23 and 24 and at their forward ends to the hangers 20, as

shown in Figs. 1 and 2.

32 and 33 indicate rods which'connectv the of the wheel axle 12, as bestshown in Figs. 2 and 3. I I

" 34 and 35 indicate cultivator gangs,.which are mounted under the Wheelaxle 12 and are connected at their forward ends to the pipeboxes 25and26 byv means oficouplingsz36; as best shown in Figs. 1 and 4.--"Each'coi1pling 36 consists of alink37,whichispivotally connected toone of the pipe-boxes 25 or 26: by

means of a bolt 38, which passes-throughbolt holesiii theforward'portion of the link and through one of the holes 27inthe'pipe-box.

Rigidly connected to each link 37 is a footlever 39, which extendsrearward therefrom substantially in a horizontal position, andisprovided with a foot-rest 40, as shown in Fig. 1. The foot lever 39 isadj ustably secured upon its link-37, and for this purpose I preforreuse a clutch 41 composed of two clutch; .95

sections adapted to be held tightly together by a bolt 42, as best shown'inFig. 1. By

loosening the bolt 42 the position of the lever 'r 39 with reference tothe link 37 maybe adjusted as desired. 1

Each disk gang 34 and 35 consists of a frame IOC 43, having dependingarms 44 and 45, by

at one end of the rear portion thereof is a horizontal plate 47, as bestshown in Fig. 5.

48 indicates a second plate, which is adapted to rest upon the plate 47,which plate 48 is provided with an upwardly projecting arm 49, as shownin Fig. 5. The plates 47 and 48 are secured together and to the diskframes 43 by bolts 50, which pass through said plates and throughbolt-holes 51 provided in the upper surface of the rear portion of thedisk frames 43. A number of holes 51 are provided in the disk frames 43to permit of adjusting the position of the plates 47 and 48. The plates47 and 48 are adapted to turn upon each other to permit of theadjustment of the frames 43 to the line of motion of the cultivator.

52 indicates an arch, best shown in Fig. 3, which arch connects the arms49 carried by the two disk frames 43, as best shown in Fig. 3. The lowerends of the arch 52 are secured to their respective arms 49 by bolts 53,in such manner as to permit of the turning of said arms upon the bolts53 as their axes. Near the upper portions of the arms 49 are providedbolt holes 54 adapted to receive a pin 55 which is adapted to passthrough the arch 52 into the holes 54 to permitof adjusting the angularposition of the arms 49 to the arch 52, and thereby providing for thevertical adjustmentof the cultivating disks, as indicated by the dottedlines in Fig. 5.

The disk frames 43 are provided attheir forward ends with bolts 56fitted in slots 57 in plates 58, in such manner that the disk frames 43may be partially rotated on a horizontal axis without moving the plates58. Each plate 58 is provided with bosses 59 and 60 adapted to receive abolt 61, which passes through suitable holes in the rear portion ofthelink 37, as shown in Fig. 1. By this construction lateral swinging ofthe disk frames 43 is permitted.

At some suitable point upon each disk frame 43 is provided a bracket 62,which is provided with a horizontal slot, as shown in Fig. 3, throughwhich slot the lever 39 passes, as best shown in Fig. 3. Each bracket 62is provided with bolt holes 63 arranged at suitable points on its uppersurface, as shown in Fig. 3.

64 and 65 indicate levers for adjusting the height of the disk gangs.The levers 64 and 65 are mounted at opposite sides of the cultivatorframe, and each lever is connected through a rigid connecting rod 66 tothe bracket which lies under it, by a bolt 67. By adjusting the point ofconnection of the rod 66 with the bracket 63 the action of the liftinglever may be varied.

68 indicates segmental racks adapted to receive pawls 69 carried by thelevers 64 and 65, for locking the levers in position.

By connecting the levers 64 and 65 with the disk-carrying frames throughthe medium of rigid connecting rods 66, a positive downward pressure maybe exerted upon the gangs separately, thereby forcing them into theground, and by locking levers the disk gangs may be held at any desireddepth. If it is desired to hold the gangs in the ground in an inclinedposition, the connecting rods 66 are connected to the brackets 62 at oneend or the other, depending upon the direction of inclination in whichthe gangs are to be held. The arrangement described enables the entireweight of the machine and rider to be thrown upon the disk-carryingframes, thereby securing a very efficient machine.

The operation of the cultivator is as follows: When the cultivatingdisks 46 are not in use, the levers 64 and 65 are thrown back, therebylifting the disks from the earth, the pipeboxes 25 and 26 turning upontheir spindles 23 and 24 and thereby permitting of such lifting of thecultivating disks. For throwing the dirt in, the disks are arranged asshown in Fig. 2, and the extent to which they will throw the dirt inwill be determined by their angle to the line of motion of thecultivator. By moving the foot lever 36 laterally the forward portion ofthe disk frames will be thrown in in the same direction in which thefoot lever is moved, thereby throwing the forward edges of the disksalso in a similar direction, as indicated by dotted lines in Fig. 4. Bythe peculiar arrangement of the coupling, devices by means of which theforward ends of the gangs are shifted to adjust the position of thedisks, a much greater leverage is obtained and the foot levers arerelieved from the greater portion of the strain upon the cultivatingdisks. The operator is thereby enabled to hold the foot lever at anydesired position by a slight pressure of the foot. This permits of veryaccurate and rapid adjustment of the disks and facilitates the avoidanceof obstructions. As the disks are adjusted to the'line of motion, theplates 47 and 48 will turn upon each other as may be necessary. When itis desired to change the depth of the furrows so that they will not allbe ofequal depth, the cultivating disks may be thrown int'b an inclinedposition by adjusting the angle of the arms 49 to the arch 52, asindicated by dotted lines in Fig. 5. Such rotation of the disk frames asmay be necessary on account of such adjustment of the disks will bepermitted by reason of the construction of the plates 58, as shown inFig. 7. To arrange the disks for throwing the dirt outward, the plates47 and 48 are moved to the opposite ends of the disk frames 43, as shownin Figs. 8 and 9, and the disk gangs 34 and 35 exchange places; that is,the gang 34 is moved to the left hand side of the machine, as shown inFig. 3, and the gang 35 to the right hand side. Theparts will then be inthe position shown in Figs. 8 and 9. By adjusting the position of theplates 47 and 48 upon the disk frames 43, the action of the foot levers39 may be varied to cause them to.

wish to limit .myselfto the-use ofdisks, as;

other suitable cultivating devices may. be

- used. Neither do I wish to limit;myself to the use of coupling linksofthe specific construction shown,- as-otherdevices could be used toaccomplish thesame result. The formshown, however, is the best known tome at;

present.

By constructing the cultivator as above described, it is particularlyadapted for use in hard soil or in replanted corn, as without leavinghis seat the operator may cause the dirt to bethrown high or low bymeans of the foot lever, and' the disks can be held in the ground at anydesired depth while the cultivator is in motion, even though there maybe hard parts and sandy soil in the same row.

A peculiar advantage lies in the fact that the operator can operate thedisks by means of the foot lever to dodge corn,- at the same timeleaving his hands freeto handle the lines.
